Silkcotton purslane is a low-growing succulent that forms dense mats with small, fleshy leaves and tiny flowers. This drought-tolerant annual blooms from June through September. Its compact size makes it suitable for ground cover or rock garden applications.

In an HOA neighborhood

Silkcotton Purslane takes more care to keep looking intentional in a front yard. Maintenance level: low. Consider it for backyard or mid-zone beds rather than the street edge.

Works well in: backyard only.

  • Mat-forming growth can appear uncontrolled
  • Annual nature means gaps and bare spots

Wildlife value
